Solution - -4hMG (0.154 m, 0.423m) 25MC 1(0,0) 36M C (-0.409 m, 0.439 m) distance Now, force between - 44 MC and 25MC . 81= √Now, foru between 25MC and - 4400 F = kg 92 9x10° X 25X10 X 44 X10 - 48.9N (0.450) 22 Now, force between 254C and 36 С. F =Now, angle made by fi with positive x-axis tono i = 0.423 0.154 tan I 0.423 0.154 70° So, angle made by Fi with positive x-ax= 22.701 47° (1) + 22.7sin 4706) = - 15.5i + 16.6; Now, ruat net force veetor. ol 14 .ר R = Fit F. - 31.00 + 30.0) + (-15.5)
